Tags -- what are they and how do we use them?

Just like the sections (personal, sewing, crafting...) each word you choose creates a link. Your own user name is a link to all the posts you created. These links and the Tags, help us find questions, answers, projects etc. I have added some pictures. Words like "the" are not useful as tags. You can edit your posts (see the Q&A) to edit your tags. If I do a project using a design created by someone other than our Miss Veronika, adding the persons name (spelling counts!) can help other Cuties return to the project later.
The last picture added shows tags that do not help us search for anything. Each "word" (in blue) is its own tag. None of them are useful tags.
